My Jones problem is the underlever on my Alex Henry .450 BPE. It's an absolute bear to get it closed. Also, unl;ike the one on my Mullin, there is no quiet "click" to indicate closure.

Could this be a sign that it was repaired in a "shade-tree gunsmith" kind of way at some time?

It really takes a lot of force, both to open and close. But closing it is definitely the more strenuous. It's tough to just get it under the flats, and then an extra measure of force to push it so that it is centered.

I've always wondered if something is amiss somewhere, just waiting to snap and turn into a major headache.

Any thoughts?
